High Mileage Synthetic Blend Motor Oils

Passenger Car Motor Oil

MAG 1® High Mileage Synthetic Blend Motor Oil is specially formulated to extend engine life for vehicles that have already exceeded 75,000 miles. It conditions seals, helps to prevent leaks, features superior oxidation stability, and provides extra protection against sludge, deposit buildup, and high temperatures. It also contains superior additives and properties that outperform conventional motor oils.

In addition, FMX® Technology creates strong, durable and high-performing oil that controls friction and wear.

So if you want longer engine life and a higher level of protection and performance than conventional motor oils, select High Mileage Synthetic Blend Motor Oil from MAG 1.

Unsurpassed Protection, Even in the Lightest Viscosity

MAG 1® with FMX® Technology provides unsurpassed protection in every viscosity. Even our lowest viscosity oils protect better than thick oils of the past. Our advanced oil chemistry actually improves oil properties through time, retaining viscosity, friction and anti-wear benefits, in spite of severe engine temperatures.

High Mileage Synthetic Blend Motor Oil featuring Evolutionary Performance™

MAG 1® with FMX® Technology – Friction Management for Xtreme protection™ provides these benefits:

Performance

Controls friction and wear better than the latest API requirements.¹ 

Strength

Provides a strong oil film to avoid metal-to-metal contact, even under extreme stress.

Durability

Stands up to the heat and shearing so it extends oil life.

¹As measured against the Sequence IV Average Cam Wear Limit for API SP.
